通过控制氮、氧混合气体中的氧含量,650℃保温30 min,在武钢510 L热轧带钢表面制备氧化皮.采用SEM、XRD、电化学测试方法研究了不同结构氧化皮的热轧带钢在3.5 wt%NaCl溶液中的腐蚀行为.结果表明,氧浓度5%时,所制备的氧化皮没有分层,只含有Fe3O4和Fe颗粒,厚度仅为6 μm左右;氧浓度在10%～60%时,所制备的氧化皮结构均为表层Fe2O3较薄,中间层Fe3O4最厚,内层Fe3O4和Fe混合相.氧浓度10%时,其氧化皮厚度约15 μm,表层Fe2O3量较少,与Fe3O4层界限模糊;当氧浓度＞10%时,其氧化皮厚度均为20 μm左右,与氧浓度10%相比,表层Fe2O3量略有增加,Fe2O3层与Fe3O4层界限分明;不同供氧条件下制备的热轧带钢氧化皮的耐蚀性能由好到差依次为:20%、10%、30%、60%、5%.
